If 93L does develop, its track evolution will be complicated by an upper-level low that is forecast to develop offshore of the Carolinas and then drift westward. It's eventual movement would then depend on how strong it gets, whether or not the upper-system tries to develop a surface low of its own, and how far west the upper sytem actually moves.

Right now, 93L is still pretty disorganized, with an apparent surface center over the far eastern Dominican Republic, a possible mid-level circulation south of Puerto Rico, and who knows what going on underneath the strongest convection to the south of those regions. The current recon mission seems to be focusing on the surface center. NHC has downgraded the potential for tropical cyclone development from high to medium. Any significant development may have to wait until the current surface center moves away from Hispaniola, or otherwise reforms in an area closer to the deep convection.
